Abstract: A mobile router offers seamless roaming services to one or more locally connected mobile hosts over one or more simultaneously connected networks. The mobile router, as well as its local area network, roams across different subnets on similar networks, across networks that are dissimilar, or across a simultaneous combination of both. Simultaneous support is provided for mobile hosts configured for static IP addressing and mobile hosts configured for dynamic IP addressing. Seamless support is provided for mobile hosts that dynamically migrate from one mobile router to another mobile router, while avoiding the need for configuration settings on the mobile router that are associated with individual mobile hosts and avoiding the need for mobility support software on the mobile hosts themselves.

Abstract: A method is provided for broadcasting a packet over multiple dissimilar wireless networks, at least one of the networks natively supporting broadcasting and at least one of the networks not natively supporting broadcasting. The method includes determining whether the packet is to be broadcast; and when the packet should be broadcast, determining recipients of the packet. A current network over which the packet will be broadcast is then selected based upon the determined recipients. Subsequently, it is determined whether the current network supports broadcasting. When the current network does not natively support broadcasting, the packet is individually sent to each recipient over the current network. When the current network does natively support broadcasting, the packet is broadcasted to the recipients over the current network.

Abstract: A method is provided for seamless roaming over multiple dissimilar wireless networks leveraging a set of one or more SDRs, and possibly some traditional radio communication devices. The method includes determining whether alternate networks are available regardless of whether the SDR has only a single transmitter and receiver or multiple transmitters and receivers. In addition, if the SDR provides multiple transmitters and receivers, or if multiple distinct SDRs are available to the mobile computing device, the method will be able to better optimize the seamless roaming experience for the user while still utilizing the set of SDRs, in part, to determine whether alternate networks are available. The method further includes managing the transitions of an SDR between various modulation algorithms according to a variety of states and settings of the SDR or of the set of SDRs as a whole.

Abstract: A method manages the flow of packetized data over multiple dissimilar wireless networks. The method includes assigning a weight to each of the wireless networks, and allocating a portion of the packetized data to each network based upon the assigned network weights. Finally, the allocated data is simultaneously sent across the corresponding wireless networks.
